Red Sox reliever Tyler Thornburg will undergo season-ending surgery for thoracic outlet syndrome on Friday, Evan Drellich of CSN New England reports.
Thornburg, 28, never pitched in a Red Sox uniform since the club acquired him from the Brewers in December. He started developing arm issues early in spring training and never recovered.
Across parts of five seasons in the majors, Thornburg has a career 2.87 ERA with a 220/91 K/BB ratio in 219 2/3 innings. He was particularly impressive last season, when he saved 13 games and struck out 90 batters with a 2.15 ERA for the Brewers.
MLB.com’s Mark Feinsand reports that there is some momentum in talks between the Mariners and free agent outfielder Jon Jay.
Jay, 32, hit .296/.374/.375 in 433 plate appearances with the Cubs last season, which is adequate. He’s heralded more for his defense and his ability to play all three outfield spots.
The Mariners are losing center fielder Jarrod Dyson to free agency and likely don’t want to rely on Guillermo Heredia next season, hence the interest in Jay. The free agent class for center fielders is otherwise relatively weak.
